Design a Custom BoardAbout This Component
Dual-channel constant-current LED driver with 32 linear dimming levels and external resistor current programming. Features 50 mV low dropout at 20 mA, enabling direct battery operation from 2.4–5.5 V inputs. Individual control loops maintain tight current matching across channels while supporting wide LED forward voltage ranges. Includes thermal shutdown, 1-wire dimming interface, and sub-1 µA shutdown current for portable displays and handheld devices.
Package: SOT-363 · 6 pins
Why does this need a breakout?
SOT-363 packages are tiny surface-mount devices with 0.65mm pin pitch, making hand-soldering risky and breadboard use impossible. A breakout board breaks out the 6 pins to standard 0.1" spacing, enabling reliable prototyping of MOSFETs, transistors, and level shifters without microscopy or specialized equipment.
